Modes for Carrying Out the Invention
[0024] Hereinafter, a plate-like component and a top plate accessory according to an embodiment of the present invention will be described based on the drawings.
[0025] <Top plate accessory> FIG. 1 is an exploded view showing a top plate accessory 100 according to an embodiment of the present invention. As shown in Figure 1, the furniture with a tabletop 100 according to this embodiment comprises a plate-shaped component 1 and a support structure 2. The furniture with a tabletop 100 is a table (high table) used by being placed on the floor surface F of, for example, an office or a conference room in a public facility. In the furniture with a tabletop 100, the plate-shaped component 1 is also referred to as the tabletop.
[0026] In the following explanation, the direction that intersects (for example, perpendicular to) the floor surface F is referred to as the vertical direction Z. The vertical direction Z may be, for example, parallel to gravity (i.e., vertical) or inclined with respect to the vertical direction. One direction that intersects (for example, perpendicular to) the vertical direction Z is referred to as the width direction X. The direction that intersects (for example, perpendicular to) both the vertical direction Z and the width direction X is referred to as the depth direction Y. The width direction X and the depth direction Y may be perpendicular to gravity (i.e., horizontal) or inclined with respect to the horizontal direction. Along the vertical direction Z, the direction moving away from the floor surface F towards the top-mounted fixture 100 is referred to as upward, and is represented by the +Z direction in the diagram. The direction opposite to upward is referred to as downward, and is represented by the -Z direction in the diagram. One direction along the width direction X is referred to as rightward, and is represented by the +X direction in the diagram. The direction opposite to the right is called the left, and is represented by the -X direction in the diagram. One direction along the depth direction Y is called the rear or far side, and is represented by the +Y direction in the diagram. The direction opposite to the rear is called the front or near side, and is represented by the -Y direction in the diagram. Viewing from the vertical direction Z is called a plan view. In the width direction X, the direction toward the center O in a plan view of the plate-shaped part 1 (first plate part 10) is sometimes called the "inside of the width direction X," and the direction away from the center O is sometimes called the "outside of the width direction X." Similarly, in the depth direction Y, the direction toward the center O is sometimes called the "inside of the depth direction Y," and the direction away from the center O is sometimes called the "outside of the depth direction Y." In addition, a direction that intersects (for example, is perpendicular to) the vertical direction Z is called the intersecting direction. The width direction X and depth direction Y described above are examples of intersecting directions. In the direction of intersection, the direction toward the center O is sometimes referred to as the "inside direction of intersection." In the direction of intersection, the direction away from the center O is sometimes referred to as the "outside direction of intersection."
[0027] <Support structure> The support structure 2 has at least one ground contact portion CT that contacts the floor surface F. In the illustrated example, the support structure 2 has four legs 2a connected to the plate-shaped component 1 (more specifically, the second outer surface 21a described later). A ground contact portion CT is provided at the lower end of each leg 2a. However, the shape and configuration of the support structure 2 are not particularly limited as long as the plate-shaped component 1 can be supported from below, and can be modified as appropriate.
[0028] <Plate-shaped parts> Figure 2 is a cross-sectional view along the line II-II shown in Figure 1. Figure 3 is a cross-sectional view along the line III-III shown in Figure 1. Figure 4 is a cross-sectional view along the line IV-IV shown in Figure 1. Figure 5 is a cross-sectional view along the line VV shown in Figure 1. As shown in Figures 1 to 5, the plate-shaped component 1 according to this embodiment comprises a first plate portion 10, a second plate portion 20, a shielding component 30, a plurality of (four in the illustrated example) corner components 40, a plurality of (ten in the illustrated example) first reinforcing members 51, a plurality of (four in the illustrated example) second reinforcing members 52, a third reinforcing member 53, a lid portion 60, a support portion 70, and a duct component 80.
[0029] <Main body> In this embodiment, the first plate portion 10, the second plate portion 20, and the multiple corner parts 40 are sometimes collectively referred to as the "main body portion M". In this embodiment, the main body portion M has a plate-like shape due to the combination of the first plate portion 10, the second plate portion 20, and the multiple corner parts 40. As shown in Figures 2 to 5, the main body portion M has an internal space IS and an opening 90.
[0030] <First panel section> As shown in Figures 1 and 2, the first plate portion 10 according to this embodiment has a base portion 11 and a plurality (four in the illustrated example) bent portions 13. The first plate portion 10 is made of metal. The first plate portion 10 may be made of a metal plate such as a steel plate. In this embodiment, the direction perpendicular to the first plate portion 10 (base portion 11) (orthogonal direction) coincides with the vertical direction Z.
[0031] The base portion 11 is a plate-like part that extends in the width direction X and the depth direction Y.
[0032] As shown in Figures 1 and 2, the base portion 11 (first plate portion 10) has a first outer surface 11a and a first opposing surface 11b. The first opposing surface 11b is located on the opposite side from the first outer surface 11a. In this embodiment, the first outer surface 11a faces upward, and the first opposing surface 11b faces downward. The first outer surface 11a faces the opposite side from the second plate portion 20 in the vertical direction Z.
[0033] The outer peripheral edge portion 12 is the part of the base portion 11 that is located on the outer peripheral edge of the base portion 11 (first plate portion 10) in a plan view. As shown in Figure 1, the outer peripheral edge portion 12 has an annular shape in a plan view. In this specification, the term "annular shape" does not mean only a circular annular shape, but also includes shapes other than an annular shape, such as a rectangular annular shape. "Annular shape" can also be read as "loop shape" or "closed loop shape". The outer peripheral edge portion 12 according to this embodiment has four straight portions 12a and four curved portions 12b.
[0034] Each straight section 12a extends in a straight line in a plan view. More specifically in this embodiment, two of the four straight sections 12a extend in the width direction X, and the remaining two straight sections 12a extend in the depth direction Y. Furthermore, these four straight sections 12a are arranged to form a rectangular shape with sides extending in the width direction X and the depth direction Y. As a result, the base 11 has a substantially rectangular shape in a plan view.
[0035] Each curved section 12b extends in a curved shape (for example, an arc shape) in a plan view. Specifically, each curved section 12b has a curved shape that is convex outward in the direction of intersection. The four curved sections 12b and the four straight sections 12a are arranged alternately along the outer edge 12. Each curved section 12b extends so as to connect two adjacent straight sections 12a. Each curved section 12b constitutes a corner of the base 11 (first plate section 10) in a plan view.
[0036] In the illustrated example, the width X dimension of the base 11 (first plate portion 10) is longer than the depth Y dimension of the base 11 (first plate portion 10). However, the width X dimension of the base 11 (first plate portion 10) may be less than or equal to the depth Y dimension of the base 11 (first plate portion 10).
[0037] As shown in Figures 1 and 2, the bent portion 13 is connected to the straight portion 12a of the base portion 11 (first plate portion 10). As shown in Figure 2, the bent portion 13 according to this embodiment has a first bent portion 13a, a second bent portion 13b, and a third bent portion 13c.
[0038] The first bent portion 13a is the portion that extends downward from the outer peripheral edge (straight portion 12a) of the base portion 11. The second bent portion 13b is the portion that extends inward in the intersecting direction (towards the -Y side in the example of Figure 2) from the lower end of the first bent portion 13a. The third bent portion 13c is the portion of the second bent portion 13b that extends upward from the inner end in the intersecting direction.
[0039] The first bent portion 13a has an outer surface 13a1 facing outward in the intersecting direction (towards the +Y side in the example of Figure 2). The outer surface 13a1 constitutes a part of the outer surface (i.e., the surface facing outward in the intersecting direction) of the first plate portion 10 (plate-shaped component 1, main body portion M).
[0040] The bent portion 13 described above is formed by bending the metal plate constituting the first plate portion 10 toward the first opposing surface 11b side (i.e., downward side) in the portion corresponding to the straight portion 12a. As shown in Figures 1 and 3, the curved portion 12b of the base portion 11 does not have the bent portion 13 described above.
[0041] As shown in Figures 1, 4, and 5, an opening 11c is formed in the base portion 11 (first plate portion 10). The opening 11c opens into the first outer surface 11a and extends downward, penetrating the base portion 11 (first plate portion 10) in the vertical direction Z. In other words, the opening 11c opens into both the first outer surface 11a and the first opposing surface 11b.
[0042] As shown in Figure 1, the opening 11c according to this embodiment is located in the central part (the part including the center O) of the first plate portion 10 in a plan view. The opening 11c according to this embodiment has a rectangular shape including a pair of long sides 11c1 extending in the width direction X and a pair of short sides 11c2 extending in the depth direction Y.
[0043] <Second board section> The second plate portion 20 is located below the first plate portion 10 (on the first opposing surface 11b side) and is positioned to overlap the first plate portion 10 in a plan view. As shown in Figures 2 to 5, the second plate portion 20 is spaced apart from the first plate portion 10 in the vertical direction Z. The second plate portion 20 is made of metal. The metal forming the second plate portion 20 may be the same as the metal forming the first plate portion 10. The second plate portion 20 may be made of a metal plate such as a steel plate.
[0044] As shown in Figure 1, the base portion 21 is a plate-shaped part that extends in the width direction X and the depth direction Y. The base portion 21 is provided in a position that overlaps with the base portion 11 of the first plate portion 10 in a plan view. As shown in Figure 2, the base portion 21 is positioned with a gap in the vertical direction Z relative to the base portion 11.
[0045] As shown in Figures 1 and 2, the base portion 21 (second plate portion 20) has a second outer surface 21a and a second opposing surface 21b. The second opposing surface 21b is located on the opposite side from the second outer surface 21a. The second opposing surface 21b faces the first opposing surface 11b in the vertical direction Z. In this embodiment, the second outer surface 21a faces downward, and the second opposing surface 21b faces downward. The second outer surface 21a may be provided with a fixing mechanism (not shown, for example, a screw hole) for fixing the support structure 2.
[0046] The outer peripheral edge portion 22 is the part of the base portion 21 located at the outer peripheral edge of the base portion 21 (second plate portion 20) in a plan view. As shown in Figure 1, the outer peripheral edge portion 22 has an annular shape in a plan view. The shape of the outer peripheral edge portion 22 corresponds to the shape of the outer peripheral edge portion 12 described above. That is, the outer peripheral edge portion 22 according to this embodiment includes four straight portions 22a and four curved portions 22b, similar to the outer peripheral edge portion 12.
[0047] Each straight section 22a extends linearly along the straight section 12a in a plan view. Specifically, two of the four straight sections 22a extend in the width direction X, and the remaining two extend in the depth direction Y. Furthermore, these four straight sections 22a are arranged to form a rectangular shape with sides extending in the width direction X and the depth direction Y. As a result, the base 21 has a substantially rectangular shape in a plan view.
[0048] Each curved section 22b extends along the curved section 12b in a curved shape (e.g., an arc shape) in a plan view. Specifically, each curved section 22b has a curved shape that is convex outward in the direction of intersection. The four curved sections 22b and the four straight sections 22a are arranged alternately. Each curved section 22b extends so as to connect two adjacent straight sections 22a. Each curved section 22b constitutes a corner of the base section 21 (second plate section 20) in a plan view.
[0049] As shown in Figures 1 and 2, the bent portion 23 is connected to the straight portion 22a of the base portion 21 (second plate portion 20). As shown in Figure 2, the bent portion 23 according to this embodiment has a first bent portion 23a and a second bent portion 23b.
[0050] The first bent portion 23a is a portion that extends upward from the outer peripheral edge (straight portion 22a) of the base portion 21. The second bent portion 23b is a portion that extends inward in the intersecting direction from the upper end of the first bent portion 23a.
[0051] As shown in Figure 2, the upper surface of the second bent portion 23b contacts the first opposing surface 11b of the first plate portion 10. In this embodiment, the second plate portion 20 is fixed to the first opposing surface 11b by welding the upper surface of the second bent portion 23b to the first opposing surface 11b.
[0052] In both the width direction X and the depth direction Y, the second plate portion 20 is formed to be slightly smaller than the first plate portion 10. Specifically, the dimensions of the second plate portion 20 are set to be smaller than those of the first plate portion 10 to the extent that, when the second plate portion 20 is fixed to the first opposing surface 11b, the bent portion 23 is located on the inside in the intersecting direction of the bent portion 13 (towards the -Y side in the example of Figure 2). More specifically, when the second plate portion 20 is fixed to the first opposing surface 11b, the first bent portion 23a of the bent portion 23 and the third bent portion 13c of the bent portion 13 face each other in the intersecting direction (depth direction Y in the example of Figure 2). As shown in the example of Figure 2, when the second plate portion 20 is fixed to the first opposing surface 11b, the lower surface of the base portion 21 and the lower surface of the bent portion 13 (the lower surface of the second bent portion 13b) may be located on the same plane.
[0053] As shown in Figures 1 and 3, the curved portion 22b (corner portion) of the second plate portion 20 does not have the aforementioned bent portion 23. As shown in Figure 3, in the curved portion 22b, a notch 21d is formed in the base portion 21 that opens outward in the intersecting direction. The notch 21d penetrates the base portion 21 in the vertical direction Z. A corner component 40 (specifically, the bottom wall portion 43, which will be described later) is placed in the notch 21d.
[0054] As shown in Figures 1, 4, and 5, an opening 21c is formed in the base portion 21 (second plate portion 20). The opening 21c opens onto the second outer surface 21a and extends upward, penetrating the base portion 21 (second plate portion 20) in the vertical direction Z. In other words, the opening 21c opens onto both the second outer surface 21a and the second opposing surface 21b.
[0055] The opening 21c is positioned to overlap with the opening 11c in a plan view. The shape of the opening 21c corresponds to the shape of the opening 11c. Specifically, the opening 21c according to this embodiment has a rectangular shape, similar to the opening 11c, including a pair of long sides 21c1 extending in the width direction X and a pair of short sides 21c2 extending in the depth direction Y (see Figure 1).
[0056] <Corner parts> As shown in Figures 1 and 3, the corner component 40 is a component fixed to the first opposing surface 11b of the first plate portion 10 at the curved portion 12b (corner portion) of the first plate portion 10. As shown in Figure 3, the corner component 40 according to this embodiment has a fixing portion 41, a side wall portion 42, and a bottom wall portion 43. The corner component 40 having portions 41 to 43 may be formed, for example, by bending a metal plate.
[0057] The fixing portion 41 is the part that is fixed to the first opposing surface 11b. The fixing portion 41 has a fixing surface 41a that is fixed to the first opposing surface 11b. In this embodiment, the fixing surface 41a faces upward.
[0058] The side wall portion 42 is the part of the fixing portion 41 that is connected to the outer end in the intersecting direction. The side wall portion 42 extends away from the first opposing surface 11b in the vertical direction Z (i.e., downward). The side wall portion 42 has an outer surface 42a that faces outward in the intersecting direction. The outer surface 42a constitutes a part of the outer surface of the plate-shaped component 1 (main body portion M). The outer surface 42a extends away from the first opposing surface 11b in the vertical direction Z. In a plan view, the side wall portion 42 (outer surface 42a) extends in a curved shape along the curved portion 12b (see Figure 1).
[0059] The bottom wall portion 43 is the part connected to the lower end of the side wall portion 42. The side wall portion 42 extends inward in the intersecting direction. The lower surface of the bottom wall portion 43 may be on the same plane as the lower surface of the base portion 21.
[0060] At least a portion of the gap GP (see Figure 3) that may occur between the first plate portion 10 and the corner portion 40 may be filled, for example, with a solidified paint film of the paint used to paint the main body portion M. Alternatively, the gap GP may be narrowed or eliminated by bending (compressing) the curved portion 12b (corner portion) of the first plate portion 10 downward.
[0061] <Interior space> As shown in Figures 2 to 5, the internal space IS is located between the first plate portion 10 and the second plate portion 20 in the vertical direction Z. The internal space IS is a space formed inside the main body portion M. More specifically in this embodiment, the internal space IS corresponds to the space enclosed by the first opposing surface 11b of the first plate portion 10, the second opposing surface 21b of the second plate portion 20, the first bent portion 23a of the bent portion 23 (see Figure 2), the side wall portion 42 of the corner component 40 (see Figure 3), and the shielding wall portion 31 of the shielding component 30 (details will be described later; see Figures 4 and 5). In this embodiment, the internal space IS has a ring shape in plan view that surrounds the opening 90 (openings 11c, 21c).
[0062] <Opening> As shown in Figures 4 and 5, the opening 90 according to this embodiment opens into both the first plate portion 10 and the second plate portion 20. That is, the opening 90 according to this embodiment penetrates both the first plate portion 10 and the second plate portion 20 in the vertical direction Z. For example, wiring for electronic equipment or the like, which is placed on the first plate portion 10, is inserted through the opening 90.
[0063] Hereinafter, the plate portion 10 and 20 through which the opening 90 is formed may be referred to as the "opening plate portion." In this embodiment, both plate portions 10 and 20 are opening plate portions. The opening 90 may be formed in only one of the first plate portion 10 and the second plate portion 20. In other words, the opening 90 only needs to be formed in at least one of the first plate portion 10 and the second plate portion 20. To put it another way, at least one of the first plate portion 10 and the second plate portion 20 needs to be an opening plate portion.
[0064] The opening 11c formed in the first plate portion 10, which is an opening plate portion, functions as a first opening edge portion 91 that defines the opening edge of the opening 90. Similarly, the opening 21c formed in the second plate portion 20, which is an opening plate portion, functions as a second opening edge portion 92 that defines the opening edge of the opening 90. The opening edges 91 and 92 (openings 11c and 21c) have an annular shape in plan view (see Figure 1).
[0065] As shown in Figures 4 and 5, the opening 90 is adjacent to the internal space IS in a direction that intersects it (width direction X in the example of Figure 4; depth direction Y in the example of Figure 5). In other words, the opening 90 and the internal space IS are aligned in a direction that intersects it. To put it another way, the opening 90 and the internal space IS are at least partially coincided in position in the vertical direction Z. In this embodiment, the opening 90 and the internal space IS are adjacent in a direction that intersects it via the shielding component 30.
[0066] <Shielding components> As shown in Figures 4 and 5, the shielding component 30 is positioned to cover the internal space IS when viewed through the opening 90. More specifically in this embodiment, whether the internal space IS is viewed from the opening 11c side (upwards in the vertical direction Z) through the opening 90 (first viewpoint), or from the opening 21c side (downwards in the vertical direction Z) through the opening 90 (second viewpoint), or from a region of the opening 90 adjacent to the internal space IS in a direction intersecting with the internal space IS (third viewpoint), the area on the far side in the width direction X or depth direction Y of the internal space IS adjacent to the opening 90 is shielded by the shielding wall portion 31 of the shielding component 30, which will be described later. As a result, the shielding component 30 suppresses the exposure of the internal space IS to the opening 90. Note that the shielding component 30 does not necessarily have to be positioned to cover the internal space IS in all of the first to third viewpoints. In other words, the shielding component 30 may be positioned so as not to cover the internal space IS from one or two of the first to third viewpoints. That is, the shielding component 30 only needs to be positioned so as to cover the internal space IS from at least one of the first to third viewpoints.
[0067] The shielding component 30 is made of metal. The metal forming the shielding component 30 may be the same as the metal forming the first plate portion 10. The metal forming the shielding component 30 may be the same as the metal forming the second plate portion 20.
[0068] As shown in Figure 1, the shielding component 30 according to this embodiment is formed separately from both the first plate portion 10 and the second plate portion 20. In a plan view, the shielding component 30 according to this embodiment has an annular shape along the opening edges 91 and 92 (openings 11c and 21c).
[0069] Figure 6 is an exploded view showing the shielding component 30 according to this embodiment. As shown in Figure 6, the shielding component 30 according to this embodiment includes a first shielding member 30A and a second shielding member 30B formed separately from the first shielding member 30A. As shown in Figures 1 and 6, the first shielding member 30A and the second shielding member 30B are combined to form a ring shape along the opening edges 91 and 92. In the illustrated example, the shielding members 30A and 30B are combined in the depth direction Y, but the direction in which the shielding members 30A and 30B are combined can be changed as appropriate, for example, in the width direction X. Furthermore, a ring-shaped shielding component 30 may be formed by combining three or more shielding members.
[0070] As shown in Figures 4 to 6, each shielding member 30A, 30B has a shielding wall portion 31 and at least one (three in the illustrated example) fixing portion 32. Each shielding member 30A, 30B having the shielding wall portion 31 and the fixing portion 32 is formed, for example, by bending a metal plate.
[0071] As shown in Figures 4 and 5, the shielding wall portion 31 is a portion that extends in the vertical direction Z. The shielding wall portion 31 covers the internal space IS when viewed in a direction intersecting the opening 90. In this embodiment, the upper end of the shielding wall portion 31 is at the same position as the first opposing surface 11b in the vertical direction Z, and the lower end of the shielding wall portion 31 is located below the second opposing surface 21b. As a result, the shielding wall portion 31 in this embodiment covers the entire internal space IS in the vertical direction Z. Furthermore, the shielding wall portion 31 in this embodiment covers at least a portion of the end face of the second plate portion 20 (base portion 21) that faces the opening 90.
[0072] However, the lower end of the shielding wall portion 31 may be at the same position as the first opposing surface 11b in the vertical direction Z. In other words, the shielding wall portion 31 does not have to cover the end face of the second plate portion 20. Also, the lower end of the shielding wall portion 31 may be above the first opposing surface 11b, and the shielding wall portion 31 may cover only a part of the internal space IS in the vertical direction Z.
[0073] As shown in Figure 6, the shielding wall portion 31 of each shielding member 30A, 30B includes a straight portion 31a, a pair of curved portions 31b, and a pair of intersecting portions 31c.
[0074] The straight section 31a is a portion that extends linearly in the width direction X when viewed from above.
[0075] The curved section 31b is a part that, in a plan view, extends in a curved shape that is convex outward in the direction of intersection. The pair of curved sections 31b are connected to both ends of the straight section 31a.
[0076] The intersection 31c is a portion that extends linearly in the depth direction Y when viewed from above. A pair of intersections 31c correspond one-to-one with a pair of curved portions 31b. Each intersection 31c is connected to its corresponding curved portion 31b and extends inward from that curved portion 31b in the depth direction Y.
[0077] As shown in Figures 4 and 5, the straight section 31a is arranged along the long sides 11c1 and 21c1 of the openings 11c and 21c, and the intersecting section 31c is arranged along the short sides 11c2 and 21c2 of the openings 11c and 21c (see also Figure 1).
[0078] As shown in Figure 6, in this embodiment, the two shielding members 30A and 30B are assembled in the depth direction Y such that their intersecting portions 31c are in contact with each other. In this embodiment, the first shielding member 30A is provided with a positioning step portion 31d at the tip of each intersecting portion 31c for positioning the intersecting portions 31c together.
[0079] Figure 7 is a cross-sectional view along the line VII-VII shown in Figure 6. As shown in Figure 7, the positioning step 31d is a portion that forms a step relative to the intersection 31c, directed outward in the width direction X (towards +X in the example of Figure 7). The positioning step 31d has a bent portion 31d1 and a shift portion 31d2.
[0080] The shift portion 31d2 is located outside the intersection portion 31c in the width direction X. In a plan view, the shift portion 31d2 extends linearly in the depth direction Y. The bent portion 31d1 is bent in a plan view so as to connect the intersection portion 31c and the shift portion 31d2.
[0081] When positioning the shielding members 30A and 30B, first, the shielding members 30A and 30B are brought close together in the depth direction Y so that the inner surface 31s1 of the bent portion 31d1 of the first shielding member 30A and the outer surface 31c1 of the intersecting portion 31c of the second shielding member 30B slide against each other. When the shielding members 30A and 30B are brought close enough, the tip of the intersecting portion 31c of the second shielding member 30B comes into contact with the inner surface 31s2 of the shift portion 31d2 of the first shielding member 30A. This positions the shielding members 30A and 30B.
[0082] As shown in Figures 4 and 5, the part to be fixed 32 according to this embodiment is fixed to the first plate portion 10 by being fixed to the first plate portion 10. The method of fixing the part to be fixed 32 to the first plate portion 10 is not particularly limited, but for example, welding or adhesive may be used.
[0083] Hereinafter, the plate portion of the plate portions 10 and 20 to which the fixed portion 32 (shielding component 30) is fixed may be referred to as the "fixing plate portion". In this embodiment, the first plate portion 10 corresponds to the fixing plate portion. The second plate portion 20 may be the fixing plate portion, or both the first plate portion 10 and the second plate portion 20 may be fixing plate portions. In other words, it is sufficient that at least one of the first plate portion 10 and the second plate portion 20 is a fixing plate portion.
[0084] As shown in Figures 4 to 6, the fixing portion 32 is connected to the upper end of the shielding wall portion 31. In this embodiment, as shown in Figure 6, each shielding member 30A, 30B has three fixing portions 32. The three fixing portions 32 are provided one each at the straight portion 31a, the intersection portion 31c located on the left (-X side), and the intersection portion 31c located on the right (+X side). Each fixing portion 32 extends outward in the direction of intersection from the corresponding portion 31a, 31c of the shielding wall portion 31.
[0085] As shown in Figures 4 and 5, each fixed portion 32 is a plate-shaped part (plate-shaped portion) that extends along the first plate portion 10, which is the fixed plate portion. Each fixed portion 32 has a fixed surface 32a. The fixed surface 32a extends in a direction perpendicular to the first plate portion 10, which is the fixed plate portion. The fixed surface 32a is the surface fixed to the first plate portion 10, which is the fixed plate portion. In this embodiment, the fixed surface 32a is an upward-facing flat surface of the fixed portion 32.
[0086] In this embodiment, the shielding component 30 is fixed to the first plate portion 10 (fixed plate portion) by fixing the fixing surface 32a to the first opposing surface 11b of the first plate portion 10. This fixing (fixing) may be performed with the positioning of the shielding members 30A and 30B described above already completed. Furthermore, the shielding component 30 according to this embodiment does not protrude upward from the first outer surface 11a. In other words, the entire shielding component 30 is located below the first outer surface 11a. Also, the fixing portion 32 does not need to be a plate-shaped portion extending along the first plate portion 10 (fixed plate portion); for example, the upper edge of the shielding wall portion 31 may be linearly welded along the first opposing surface 11b of the first plate portion 10.
[0087] Furthermore, the shielding component 30 does not have to be formed separately from the fixing plate portion. In other words, the shielding component 30 and the fixing plate portion may be formed integrally. For example, the shielding component 30 may not have a fixing portion 32, and the first plate portion 10 and the shielding wall portion 31 (shielding component 30) may be formed integrally. Such integral formation can be achieved, for example, by performing a drawing process on a metal plate.
[0088] The components that make up the main body M (in this embodiment, the plate portions 10, 20 and the corner portion 40) and the shielding portion 30 may be painted with the same paint.
[0089] <Reinforcement member> The reinforcing members 51, 52, and 53 are configured to reinforce the first plate portion 10. As shown in Figures 1 to 5, the reinforcing members 51, 52, and 53 are provided between the plate portions 10 and 20 in the vertical direction Z. That is, the reinforcing members 51, 52, and 53 are provided in the internal space IS.
[0090] As shown in Figure 1, the first reinforcing member 51 extends in the width direction X. In this embodiment, a plurality of first reinforcing members 51 are arranged with intervals in the depth direction Y. Two of the plurality of first reinforcing members 51 are arranged so as to sandwich the opening 21c between them in the width direction X.
[0091] As shown in Figure 2, the first reinforcing member 51 according to this embodiment has a fixing portion 51a, a pair of upright portions 51b, and a pair of contact portions 51c. The first reinforcing member 51 may be, for example, a so-called rectangular tube.
[0092] The fixed portion 51a is a portion that extends in the width direction X. The fixed portion 51a is fixed to the base portion 21 by any method such as screw fastening.
[0093] The pair of erected portions 51b are portions that extend upward from both ends of the fixed portion 51a in the depth direction Y.
[0094] The pair of contact portions 51c are portions that extend from the upper ends of the pair of upright portions 51b so as to move closer to each other in the depth direction Y. When the second plate portion 20 is fixed to the first opposing surface 11b, the upper surface of the contact portions 51c is in contact with the first opposing surface 11b. In this way, the first reinforcing member 51 reinforces the first plate portion 10. The upper surface of the contact portions 51c may be fixed to the first opposing surface 11b by any method such as welding. The first reinforcing member 51 may take on a so-called hat shape by having the contact portions 51c extend from the upper ends of the pair of upright portions 51b so as to move further apart from each other in the depth direction Y.
[0095] As shown in Figure 1, the second reinforcing member 52 is a thick plate-shaped member. In this embodiment, four second reinforcing members 52 are provided corresponding to the four corners of the first plate portion 10. The second reinforcing members 52 may be made of, for example, MDF (medium-density fiberboard).
[0096] The second reinforcing member 52 has a fitting hole 52a that penetrates the second reinforcing member 52 in the vertical direction Z. A fitting projection (not shown) provided on the second opposing surface 21b of the base 21 is fitted into the fitting hole 52a. In this embodiment, the fitting projection is fitted into the fitting hole 52a, thereby positioning the second reinforcing member 52 relative to the base 21. The second reinforcing member 52 may be further fixed to the base 21 by any fixing method such as adhesive.
[0097] As shown in Figures 2 and 3, the second reinforcing member 52 according to this embodiment is positioned on the first reinforcing member 51 with a predetermined gap in the vertical direction Z between it and the first opposing surface 11b. The base portion 11, which is made of a metal plate, may bend downward due to external forces applied by the user, etc., or external forces when the second plate portion 20 (bent portion 23) is pressure-bonded to the first plate portion 10 (bent portion 13). The second reinforcing member 52 contacts the first opposing surface 11b when the base portion 11 bends in this way, thereby suppressing excessive bending of the base portion 11. In this way, the second reinforcing member 52 reinforces the first plate portion 10. Furthermore, as shown in Figure 1, the second reinforcing member 52 according to this embodiment has a protruding portion 52b that protrudes outward in the intersecting direction at the curved portion 22b.
[0098] Figure 8 is an exploded view showing an enlarged view of the area around the third reinforcing member 53 according to this embodiment. As shown in Figures 1 and 8, the third reinforcing member 53 is a thick plate-like member having an annular shape in plan view. As shown in Figure 8, the third reinforcing member 53 in this embodiment is arranged to surround the shielding component 30 from the outside in the intersecting direction.
[0099] The third reinforcing member 53 may be formed from, for example, MDF (medium-density fiberboard). By using MDF, the annular third reinforcing member 53 can be easily manufactured.
[0100] The third reinforcing member 53 has a fitting hole 53a that penetrates the third reinforcing member 53 in the vertical direction Z. In this embodiment, one fitting hole 53a is formed at each end of the third reinforcing member 53 in the width direction X (see Figure 1). On the second opposing surface 21b of the base portion 21, a fitting projection 21d is provided at a position that overlaps with the fitting hole 53a in the vertical direction Z. The fitting projection 21d protrudes upward from the second opposing surface 21b.
[0101] A fitting projection 21d is fitted into the fitting hole 53a. In this embodiment, the fitting projection 21d into the fitting hole 53a positions the third reinforcing member 53 relative to the base 21 in both the width direction X and the depth direction Y. The third reinforcing member 53 may be further fixed to the base 21 by any fixing method such as adhesive.
[0102] As described above, the base portion 11, which is a metal plate, may bend downward due to external forces applied by the user, etc., or external forces applied when the second plate portion 20 (bent portion 23) is pressure-bonded to the first plate portion 10 (bent portion 13). The third reinforcing member 53 suppresses the bending of the first plate portion 10 by contacting the base portion 11, thereby reinforcing the first plate portion 10. In particular, the area around the opening 11c of the first plate portion 10 is prone to bending (deformation) due to external forces. The third reinforcing member 53 has the role of reinforcing the area around the opening 11c that is prone to bending (deformation) in this way.
[0103] Furthermore, the fitting hole 53a does not need to penetrate the third reinforcing member 53, as long as it opens to the lower surface of the third reinforcing member 53 and allows the fitting projection 21d to be fitted into it. The same applies to the fitting hole 52a of the second reinforcing member 52.
[0104] <Lid> As shown in Figures 1 and 4, the lid portion 60 shields at least a part of the opening 90 (first opening edge portion 91) from above. The lid portion 60 is configured to be removable from the opening 90. As shown in Figure 4, the lid portion 60 according to this embodiment has a lid base portion 61, a pair of supported portions 62, and a lid side edge portion 63 (see Figure 1).
[0105] The lid base 61 is a plate-shaped portion extending in the width direction X and the depth direction Y. The lid base 61 shields at least a portion of the opening 90 (first opening edge 91) from above. The dimension of the lid base 61 in the depth direction Y may be smaller than the dimension of the first opening edge 91 (base 11) in the depth direction Y. In this case, even when the lid 60 is attached to the opening 90, the lid base 61 only partially shields the first opening edge 91, and a portion of the wiring space CS, described later, is exposed to the first outer surface 11a.
[0106] A pair of supported portions 62 are connected to both ends of the lid base 61 in the width direction X. The supported portions 62 are the parts that are supported by the support portion 70 (support piece 72, described later) when the lid 60 is attached to the opening 90. The supported portion 62 according to this embodiment includes a first portion 62a extending downward from the end of the lid base 61, a second portion 62b extending inward in the width direction X from the lower end of the first portion 62a, and a third portion 62c extending upward from the inner end of the second portion 62b in the width direction X.
[0107] As shown in Figure 1, the lid edge portion 63 is a plate-like portion extending in the width direction X and the vertical direction Z. The lid edge portion 63 constitutes the side surface of the lid portion 60 facing the depth direction Y. Although detailed illustration is omitted, in this embodiment, one lid edge portion 63 is provided on the front side (-Y side) and the back side (+Y side) of the lid portion 60. Each lid edge portion 63 is connected to the side edge of the lid base portion 61 in the depth direction Y and the side edge of the supported portion 62 in the width direction X (see also Figure 4). Note that the lid portion 60 does not necessarily have lid edge portions 63.
[0108] <Support part> The support portion 70 supports the lid portion 60 when it is attached to the opening 90. As shown in Figures 1 and 4, the support portion 70 according to this embodiment has two support components 70P which are formed separately from each other. As shown in Figure 4, each support component 70P has a fixing piece 71 and a support piece 72.
[0109] The fixing piece 71 is fixed to the second outer surface 21a along the short side 21c2 of the opening 21c by any method such as screw fastening.
[0110] The support piece 72 is connected to the inner end of the fixing piece 71 in the width direction X. The support piece 72 is the part that supports the lid 60 (supported part 62) when the lid 60 is attached to the opening 90. The support piece 72 according to this embodiment includes a first part 72a extending downward from the end of the fixing piece 71, a second part 72b extending inward in the width direction X from the lower end of the first part 72a, and a third part 72c extending upward from the inner end of the second part 72b in the width direction X.
[0111] When the support piece 72 supports the supported portion 62, the second portion 62b of the supported portion 62 rests on the second portion 72b of the support piece 72. The third portion 72c of the support piece 72 serves to prevent the lid portion 60 from falling out of the opening 90.
[0112] <Duct parts> As shown in Figures 1 and 5, the duct component 80 shields the opening 90 (second opening edge 92) from below. A wiring space CS is formed in the duct component 80. The wiring space CS is a space in which wiring can be placed. The duct component 80 according to this embodiment has a pair of flange portions 81, a U-shaped portion 82, and a pair of side walls 83.
[0113] As shown in Figure 5, the pair of flange portions 81 are fixed to the second outer surface 21a along the long side 21c1 of the opening 21c by any method such as screw fastening.
[0114] The U-shaped portion 82 has a U-shape that opens upward when viewed from the width direction X. The upper end of the U-shaped portion 82 is connected to the inner end in the depth direction Y of the pair of flange portions 81. In this embodiment, the space enclosed by the U-shaped portion 82 corresponds to the wiring space CS.
[0115] As shown in Figure 1, the pair of side walls 83 are connected to both ends of the U-shaped section 82 in the width direction X. The side walls 83 block at least a portion of both ends of the wiring space CS in the width direction X. Note that the duct component 80 does not necessarily have side walls 83.
[0116] <effect> Next, the operation of the plate-shaped component 1, which is configured as described above, will be explained.
[0117] Conventionally, a plate-like component is known that has two plate-like sections made of metal, with an opening formed in the plate-like section that communicates with an internal space located between them. Such a plate-like component may be equipped with a resin shielding component to prevent the internal space from being exposed to the opening. However, the colors of the resin shielding component and the metal plate-like section are often mismatched, potentially compromising the aesthetic appeal. Furthermore, even if the shielding component and the plate-like section are painted with the same paint, the appearance after painting may differ between the resin shielding component and the metal plate-like section, again potentially compromising the aesthetic appeal.
[0118] To address this issue, in the plate-shaped component 1 of this embodiment, both the plate portions 10 and 20 and the shielding component 30 are made of metal. This allows the colors of the plate portions 10 and 20 and the shielding component 30 to be made closer, thereby enhancing the aesthetic appeal. In particular, the configuration in which the plate portions 10 and 20 and the shielding component 30 are all made of the same metal is preferable because it allows the colors of the plate portions 10 and 20 and the shielding component 30 to be matched, further enhancing the aesthetic appeal.
[0119] <Summary> As described above, the plate-shaped part 1 according to this embodiment comprises a plate-shaped main body M and a shielding part 30. The main body M has a first plate portion 10 made of metal and a second plate portion 20 made of metal, positioned to overlap with the first plate portion 10 in a plan view, and spaced apart from the first plate portion 10 in the vertical direction Z. The main body M has an internal space IS located between the first plate portion 10 and the second plate portion 20, and an opening 90 that opens to at least one of the first plate portion 10 and the second plate portion 20 and is adjacent to the internal space IS in the intersecting direction. The shielding part 30 is positioned to cover the internal space IS when viewed through the opening 90 and is made of metal. This configuration provides a plate-shaped part 1 that can improve design aesthetics.
[0120] Furthermore, the fixing plate portion to which the shielding component 30 is fixed may be only one of the first plate portion 10 and the second plate portion 20. For example, if the shielding component 30 is provided on both the first plate portion 10 and the second plate portion 20, there is a possibility that the shielding components 30 provided on both plate portions 10 and 20 will interfere with each other when fixing the second plate portion 20 to the first plate portion 10. By adopting a configuration in which the shielding component 30 is fixed to only one of the plate portions 10 and 20, this problem can be avoided. In other words, it becomes easier to manufacture the plate-shaped component 1 which has two plate portions 10 and 20 and a shielding component 30.
[0121] Furthermore, the shielding component 30 may be formed separately from both the first plate portion 10 and the second plate portion 20, and the shielding component 30 may be fixed to a fixed plate portion which is at least one of the first plate portion 10 and the second plate portion 20. With this configuration, it becomes possible to manufacture the two plate portions 10 and 20 and the shielding component 30 in separate processes, thereby avoiding the need to increase the size of the equipment used to manufacture the plate-shaped component 1.
[0122] Furthermore, the shielding component 30 has a fixing surface 32a that extends along the fixing plate and is fixed to the fixing plate. This configuration makes it easy to fix the shielding component 30 to the fixing plate.
[0123] Furthermore, the first plate portion 10 has a first outer surface 11a that faces away from the second plate portion 20 in the vertical direction Z, and the shielding component 30 does not protrude from the first outer surface 11a in the vertical direction Z. For example, if the shielding component 30 protrudes upward from the first outer surface 11a, the usability of the plate-shaped component 1 may be impaired. With a configuration in which the shielding component 30 does not protrude from the first outer surface 11a, such problems can be avoided. In other words, the usability of the plate-shaped component 1 can be improved.
[0124] Furthermore, of the first plate portion 10 and the second plate portion 20, the plate portion through which the opening 90 is formed (opening plate portion) has opening edge portions 91 and 92 that define the opening edge of the opening 90, and the opening edge portions 91 and 92 have an annular shape in plan view, and the shielding component 30 has an annular shape along the opening edge portions 91 and 92 in plan view. In other words, the opening 90 is located in a part of the plate portions 10 and 20 other than the outer peripheral edge portions 12 and 22, and does not open on the outer surface of the plate-shaped component 1. This configuration can further enhance the design of the plate-shaped component 1. Also, if the fixed plate portion and the shielding component 30 described above are integrally formed by drawing or the like, it is difficult to form the annular opening edge portions 91 and 92 and the shielding component 30 in a small size. By forming the fixed plate portion (plate portion 10, 20) and the shielding component 30 separately, it is easier to make the opening edge portions 91, 92 and the shielding component 30 compact, even when the opening edge portions 91, 92 and the shielding component 30 have an annular shape.
[0125] Furthermore, the shielding component 30 has a first shielding member 30A and a second shielding member 30B formed separately from the first shielding member 30A. The first shielding member 30A and the second shielding member 30B are combined to form a ring shape along the opening edges 91 and 92. It is difficult to form a ring-shaped shielding component 30 by press-forming a single metal plate. By making the first shielding member 30A and the second shielding member 30B separate, the two shielding members 30A and 30B can be formed separately by bending or other processes. This makes it easy to manufacture a shielding component 30 having a ring shape.
[0126] Furthermore, the fixture with a tabletop 100 according to this embodiment comprises a tabletop, which is the plate-shaped component 1 described above, and a support structure 2 that supports the tabletop from below. This configuration makes it possible to realize a fixture with a tabletop 100 that has improved design aesthetics of the tabletop.
[0127] <Variation> The technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
[0128] For example, the opening 90 may be located on the outer peripheral edges 12 and 22 of the plate portions 10 and 20, and may open onto the outer surface of the plate-shaped component 1. In other words, the openings 11c and 21c (opening edges 91 and 92) and the shielding component 30 do not necessarily have an annular shape in plan view.
[0129] Furthermore, the shielding wall portion 31 may extend in a direction inclined with respect to the vertical direction Z. In other words, the shielding wall portion 31 only needs to extend in a direction inclined with respect to the plate portions 10 and 20. As long as the shielding wall portion 31 covers the internal space IS when viewed from the opening 90, the shape of the shielding wall portion 31 can be changed as appropriate. Also, the shielding wall portion 31 does not need to cover the internal space IS around the entire circumference of the opening 90 (opening edges 91 and 92).
[0130] Furthermore, the plate-shaped component 1 does not necessarily have to include some or all of the corner component 40, reinforcing members 51, 52, 53, lid portion 60, support portion 70, and duct component 80.
[0131] Furthermore, without departing from the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments and modifications may be combined as appropriate. [Explanation of symbols]
